Изобретение относитс  к области исследовани  трени  и износа и касаетс  оценки ПРОТИВОИЗНОСНЫХ свойств смазывающих жидкостей.The invention relates to the field of friction and wear research and concerns the evaluation of the ANTI-WASTE properties of lubricating fluids.

Известен способ оценки износных свойств масел с использованием пары трени , состо щей из цилиндрического и плоского образцов , заключающийс  в том, что привод т в контакт с плоским образцом цилиндрический , подают в зону контакта смазку, привод т во вращение цилиндрический образец и нагружают пару трени  1.A known method for evaluating the wear properties of oils using a pair of friction consisting of cylindrical and flat samples consists in bringing a cylindrical contact with a flat sample, lubricating the contact zone, rotating the cylindrical sample and loading the friction pair 1 .

Известен также способ оценки противоизносных свойств смазывающих жидкостей, взаимодействующих с парой трени , включающей круглую пластину с вырезом и цилиндрический образец, заключающийс  в том, что привод т в контакт с поверхностью выреза образец, подают в зону контакта смазывающую жидкость, привод т во вращение образец и нагружают пару трени . Износ определ етс  весовым способом 2.There is also known a method for evaluating the anti-wear properties of lubricating liquids interacting with a pair of friction, including a circular plate with a cutout and a cylindrical sample, consisting of bringing the sample into contact with the cut surface, feeding the sample fluid into the contact zone, load a couple of friction. Wear is determined by the weight method 2.

Этот способ  вл етс  наиболее близким к изобретению по технической сущности и достигаемому эффекту.This method is closest to the invention in its technical essence and the effect achieved.

Недостатками известных способов  вл ютс  непосто нство удельной нагрузки в зоне контакта из-за изменени  фактической площади контакта по мере износа образцов , невозможность выделени  приработочного износа в ходе опытов и длительность испытаний.The disadvantages of the known methods are the inconsistency of the specific load in the contact zone due to the change in the actual contact area as the samples wear out, the impossibility of separating the running-in wear during the experiments, and the duration of the tests.

Целью изобретени   вл етс  повыщение точности и эффективности оценки.The aim of the invention is to improve the accuracy and efficiency of the evaluation.

Дл  этого по предлагаемому способу вырезы в пластине выполн ют в виде цилиндрических отверстий по периферии пластины , цилиндрический образец устанавливают в отверстии асимметрично к его оси, а об износе суд т по повороту пластин.For this, according to the proposed method, the cutouts in the plate are made in the form of cylindrical holes around the periphery of the plate, a cylindrical sample is installed in the hole asymmetrically to its axis, and wear is judged by the rotation of the plates.

На чертеже представлено устройство дл  реализации предлагаемого способа оценки противоизносных свойств смазывающих жидкостей.The drawing shows a device for implementing the proposed method for evaluating the anti-wear properties of lubricating fluids.

Устройство состоит из станины 1, нагрузочного механизма 2, поворотной опорной плиты 3, разъемной соединительной муфты 4, узла 5 трени , подъемной опорной плиты 6, стрелочного указател  7 поворота корпуса узла 5 трени , электродвигател  8 с кнопками 9 включени  и выключени . Поворотна  опорна  плита 3 прикреплена к станине 1 на щарнирных опорах 10 и при помощи двух откидных болтов 11 прижимаетс  к основанию станины 1. Узел 5 трени  состоит из вращающегос  корпуса 12, установленного в обойме 13 на двух шарикоподшипниках 14, и стакана 15, образующего с корпусом 12 термостатирующую рубащку . В стакане 15 на щтифтах 16The device consists of a frame 1, a loading mechanism 2, a rotary support plate 3, a detachable coupling 4, a friction unit 5, a lifting base plate 6, a switch pointer 7 for turning the body of the friction unit 5, an electric motor 8 with buttons 9 on and off. The swivel support plate 3 is attached to the frame 1 on the hinged supports 10 and is pressed against the base of the frame 1 by means of two hinged bolts 11. 12 thermostatic shrub. In a glass of 15 on the studs 16
